DAVID J. REX, OF PITTSBURG, PENNSYLVANIA.

PAPER-BOX-CREASING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 769,235, dated. September 6, 1904.

' Application filed November 9,1903. Serial No. 180,293. (No model.)

.To all whom it may concern:

Be it known that I, DAVID J. REX, of the 8 is a detached elevation of the creasing and I cutting rolls.

Like symbols of reference indicate like parts Wherever they occur.

My invention relates to an improvement in apparatus for creasing paper in the manufacture of paper boxes; and it consists in the combination of two or more pairs of creasingwheels of comparatively large diameter, eachwheel being mounted on a separate shaft and each pair of wheels being out of line with the other pair or pairs, so as to work on the paper at different portions of its length, with suitable feed devices, as is hereinafter more fully described.

I will now describe my, invention, so that others skilled in the art may manufacture and use the same.

In the drawings, 2 represents the frame of I the apparatus, having a guiding or feed table 3, over which the paper is drawn between the creasing-wheels 4 4E and 5 5, the paper being held on a suitable reel 6 at one end of the apparatus. These creasing-wheels 4t 4 and 5 5 are mounted on shafts 7 7' and 8 8, which shafts are journaled on the frame 2. The creasing-faces ofthe'se wheels are provided with a tongue and groove adapted to form, the desired crease in the paper as it. passes between them. The creasing-wheels themselves are of comparatively large diameter,

each wheel being mounted on a separate shaft and each pair of wheels being out of line with the other pair or pairs, so as to work on the paper at different portions of its length, the purpose of which, is to insure a smooth movement of the paper between the wheels and to prevent any breaking or tearing of the paper and to insure a perfect crease. The wheels 4 t and 5 5' are adjustable laterally on their shafts, so that they may be suited to differentsized Work;

At the other end of the frame 2 are the feedrolls 9 9, and beyond them are the creasing and cutting rolls 10 10. These feed-rolls and creasing and cutting rolls may be of the ordinary construction. Power is applied to the creasing and cutting rolls by any suitable means and communicated to the feed-rolls by a suitable belt.

' In the operation of my apparatus the paper is fed from the reel 6 along the feed-table 3 and between the creasing-wheels 4E tand 5 5', which are first adjusted to make the creases at the desired distance apart. passes between the Wheels is guided by the adjustable guides 12 12 on the table 3 and is drawn forward by the feed-rolls 9 9 and the creasing and cutting rolls 10 10. The paper after it passes from the rollslO 10 will be in proper form and properly creased and cut to be folded or bent into box form.

Printing devices may be located at any desired point between the reel 6 and the creasing the creases is prevented. This will be appreciated by those skilled in the art who have heretofore encountered more or less difficulty in forming proper creases, especially 1n heavy material by the ordinary creaslng apparatus.

-Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a paper-box-creasing apparatus, the

combination of two or more pairs of loose coacting creasing wheels, eachwheel being mounted on a separate shaft and movable independently of each other, and each pair of wheels being out of line with the other" pair or pairs and suitable feeding devices; substantially as described.
